Peripheral IV catheter with Bi-valve secure system

A catheter with a bi-valve assembly, comprising:

• a. a catheter shaft;
• b. a connecting cap;
• c. a catheter body extending along an axis from said connecting cap to said catheter shaft with a hub located in said catheter body containing a bi-valve assembly, said bi-valve assembly comprising:
• a stainless steel tubular guide;
• a spring;
• and
• a silicon sealing cap adapter;
• a supporting tube;
• and
• a flexible valve;
• wherein said flexible valve is fixedly adjoined to a proximal mouth of said catheter shaft and internally supported by said supporting tube, said flexible valve having a flexible perforation penetrable by said tubular guide and configured to return back to a sealed position when said tubular guide is pulled away from said flexible valve, wherein the flexible perforation opens sideward,
• wherein said tubular guide is movably installed within said hub to allow movement on an axis from said connecting cap to said proximal mouth of said catheter shaft mouth, and having said sealing cap adapter fixed around a proximal end of said tubular guide,
• wherein said tubular guide is surrounded by said spring while said spring is held between said silicon sealing cap adapter and said supporting tube, said spring is configured to push said tubular guide proximally towards said connecting cap and away from said flexible valve,
• wherein said connecting cap is adaptable to an external line,
• wherein adapting of said connecting cap to the external line pushes said silicon sealing cap adapter, thereby pushing said tubular guide to slide through said supporting tube towards said proximal mouth of said catheter shaft to the extent of penetrating through said flexible perforation in said flexible valve, thereby forming a hollow passage between the external line adapted to said connecting cap and said proximal mouth of said catheter shaft, and
• wherein the disengagement of the external line from said connecting cap allows said spring to extend and push said tubular guide to slide back towards said connecting cap, which in turn allows said flexible perforation in said flexible valve to return back to the sealed position, thereby preventing passage of substances through said proximal mouth of said catheter shaft.

A bi-valve assembly comprising:

• a stainless steel tubular guide;
• a spring;
• and
• a silicon sealing cap adapter;
• a supporting tube;
• and
• a flexible valve;
• wherein said sealing cap adapter is fixed on the proximal segment of said tubular guide, said flexible valve is suspended around the distal segment of said tubular guide and internally supported by said supporting tube such that said flexible valve is covering the distal opening of said tubular guide,
• wherein said flexible valve having a flexible perforation penetrable by said tubular guide and configured to return back to a sealed position when said tubular guide is pulled away from said flexible valve,
• wherein said tubular guide is surrounded by said spring while said spring is held between said sealing cap adapter and said supporting tube, said spring is configured to push said tubular guide proximally towards said connecting cap and away from said flexible valve.
